Insertion in the second exon, within coding sequences. Transcription in this mutant initiates within the P-element, just downstream of the 3' end of the w
sequences. Translation is predicted to begin at the last three nucleotides of P-element sequence and continue in-frame into nbs
sequences. In the predicted translation product, the first residue of the first BRCT domain is changed from Leu to Met, but the domain is otherwise intact. The nbs
N-terminal FHA domain is missing in this product as the insertion occurs downstream of the sequence coding this domain.
